Least Common Multiple of 38/68,321/57,991/742

Given numbers are 38/68,321/57,991/742

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 38,321,991

Least Common Multiple of Numerators i.e. LCM of 38,321,991 is 12088218.

GCF of Denominators means GCF of 68,57,742 as per the given fractions.

GCF of 68,57,742 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 38,321,991

LCM of Fractions 38/68,321/57,991/742 is 12088218

Given numbers has no common factors except 1. So, there LCM is their product i.e 12088218

Least Common Multiple of 38,321,991 with GCF Formula

Least Common Multiple of 38,321,991 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 38,321,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(38,321,991) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(38,321,991) x common factors =1 x 1 = 1

LCM(38,321,991) = ( 38 × 321 × 991 ) / 1

LCM(38,321,991) = 12088218 / 1

LCM(38,321,991) = 12088218


Lets's calculate GCF of 68,57,742

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 12088218/1

Therefore the LCM of Fractions 38/68,321/57,991/742 is 12088218
